Description

Technical Field

[0001] The utility model relates to the technical field of coil cover plates, in particular to a motor coil cover plate. Background Technique

[0002] When a motor winds coils, burrs exist on the outer edges of the iron core and the rotor due to processing problems. During the process of coil winding, the wire group may be damaged, resulting in the breakage of the insulating layer on the outer surface of the wire group, that is, the enameled wire. When the coil is in direct contact with the iron core and the rotor, problems such as inter-turn leakage may occur, and even the motor cannot work. Therefore, an insulating cover plate is covered on the iron core and the rotor bracket to separate the coil from the iron core and the rotor bracket, avoiding direct contact between the two. At the same time, the insulating cover plate is used to guide and position the winding of the coil and position the wire heads.

[0003] The existing hooks on the insulating cover plate all face downward. It is necessary for the coil to pass through the hooks in sequence. When winding the coil, it is not convenient and it is necessary to repeatedly determine whether the coil is wound in place. Therefore, in order to improve the winding efficiency of the coil, this motor coil cover plate is designed. Content of the Utility Model

[0004] The purpose of the utility model is to provide a motor coil cover plate. Through the baffle formed obliquely upward, the coil can be embedded in the hook through the gap between the baffle and the top plate, and the opening of the hook faces upward, improving the winding efficiency of the coil.

[0005] The utility model provides the following technical solution: a motor coil cover plate, including an annular cover plate body. A plurality of hooks are formed on the inner wall of the cover plate body. The hook includes a side plate and a bottom plate formed on the inner wall of the cover plate body. The bottom plate is formed on the bottom of the side plate. An upward baffle is formed on the end face of the bottom plate close to the center of the circle. The baffle is inclined outward, and there is a gap between the baffle and the side plate.

[0006] In order to further reduce the possibility of the coil slipping off, a top plate is further formed on the inner wall of the side plate. The top plate is located above the bottom plate. The top plate is located outside the baffle, and there is also a gap between the top plate and the baffle.

[0007] In order to avoid interference between the bottom plate 22 and the stator bracket, the bottom surface of the bottom plate is higher than the bottom surface of the cover plate body.

[0008] In order to facilitate the limit of the installation position of the cover plate, an upward folding edge is formed at the upper end of the cover plate body, and an outward folding edge is formed downward at the other end of the upward folding edge.

[0009] In order to enable the cover plate to be mass-produced, the cover plate body and the hook are injection-molded.

[0010] Compared with the prior art, the beneficial effects achieved by the present utility model are as follows: By forming the baffle obliquely upward, the coil can be embedded in the hook through the gap between the baffle and the top plate, and the opening of the hook faces upward, making it more convenient to wind the coil and improving the winding efficiency of the coil.

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model. Embodiment

[0018] Please refer to Figures 1 to 3 , the present utility model provides a technical solution: a motor coil cover plate, including an annular cover plate body 1, and a plurality of hooks 2 are formed on the inner wall of the cover plate body 1. The hook 2 includes a side plate 24 and a bottom plate 22 formed on the inner wall of the cover plate body 1. The bottom plate 22 is formed on the bottom of the side plate 24. A baffle 23 is formed upward on the end face of the bottom plate 22 close to the center of the circle. The baffle 23 is distributed obliquely upward and is biased outward in the diameter direction. There is a gap between the baffle 23 and the side plate 24, so that the opening of the hook 2 faces upward. The coil can be conveniently embedded in the hook 2 through the gap, improving the winding efficiency of the coil. At the same time, the baffle 23 can limit the coil to prevent the coil from slipping out of the hook 2.

[0019] As Figure 3 shown, a top plate 21 is also formed on the inner wall of the side plate. The top plate 21 is located above the bottom plate 22 and outside the baffle 23. There is also a gap between the top plate 21 and the baffle 23. The top plate 21 further limits the upper part of the coil to prevent the coil from slipping off. At the same time, the setting of the top plate 21 further reduces the size of the gap, reduces the possibility of the coil slipping off, and makes the winding of the coil more stable.

[0020] The bottom surface of the bottom plate 22 is higher than the bottom surface of the cover body 1, so that the lower end of the cover body 1 can extend downward, which is convenient for inserting the cover body 1 onto the stator bracket to complete the connection between the cover and the stator bracket, and at the same time can prevent interference between the bottom plate 22 and the stator bracket.

[0021] An upper flanging 12 is formed at the upper end of the cover body 1, and an outer flanging 11 is formed downward at the other end of the upper flanging 12. A 7-shaped flanging is formed by the upper flanging 12 and the outer flanging 11. The cover body 1 is buckled onto the stator bracket by using this flanging, which improves the installation efficiency of the cover.

[0022] The cover body 1 and the hook 2 are integrally formed by injection molding, enabling mass production of the cover.

[0023] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
